MACHINE 530R GATHERING THE EDGES OF MATTRESSES FOR STITGHIN G.

To all whom it may concern.-

Be it known that I, ITENRY A. STENGEL, a citizen of the United States,residing at Dayton, in the countyof Montgomery and have invented certainnew and useful Improvements in Machines for to be specified;

cured to ,one side of the table frame Gathering the Edges of Mattressesfor Stitching; and I dodeclare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing bad to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

This invention comprises a machine for gathering the edges of mattressespreparatory to stitching the same novel and desirable featureshereinafter described and claimed. 1

Preceding, a detailed description of the in vention, reference is madeto the accompanying drawings, of which Figure 1, is a front elevation ofthe ma.- chine showing the mechanism acting upon a mattress, a portionof which is broken away, and the mattress table and the supporting frameshown in section as partly broken away. Fig. 2, .is an elevation of Fig.1 looking from the left in Fig. 1'.

said table, said rollers .bein'g flanged to run upon tracks 26 tin saidtable frame. Se-

2 is a plate 1 providing bearings for certain parts Extendingperpendicularly from the, plate 1 is an upright plate 3 which providesvarious bearings for the gearing and other parts as illustrated in thedrawings. The upper portion of this plate 3 lies at right angles and isprovided with an an gular metallic plate 4 which incloses the upper edgeof the mattress 6 as the said mattress is moved upon the table 5.

31 designates two gathering arms which have their inner ends 35terminating at brace the opposite sides of the mattress at the edges.The gripping ends of said fingers Specification of Letters Patent.Application filed April 10. 1907. Serial No. 367,309.

lie on the inner sidesof the guide walls 4 and the outer ends of saidfingers are pivoted to i the upright plate 3 at 32. l 28 designates twoneedles that enter i openings 30 in the guide walls 4 and are i made topenetrate the mattress at the edge to com press the eXcelsior or otherfilling 37, prior to the engaging of the mattress by the fingers 31.Theseneedles 28 are swiveled to spur gears 10 and 12 at 29 and as saidgears are opening the needles work in and out of the edge of themattress from both sides, first, penetrating the mattress at the edge tocompress thefilling in the edge thereof immediately after which thefingers 31 engage the mattress and prepare it for stitching. The loweredge 36 of the mattress has been stitched and completed. It wlll beunderstood that only one edge of the mattress is operated upon at a timeby the nee- -dles 28 and. the gathering fingers 31.

The power is introduced to the machine through .shaft 6 which carries abevel gear 7 meshing with a bevel gear 8, the latter being on shaft 8mounted in the plate 3 and upon which'is also mounted a spur gear 9. Thespur gear 9 drives the two gears 10 and 12 through which the needles 2Sand the fingers 31 are operated," gear 12 being driven by anintermediate gear 1]. The gears 10 and 12 carrying the needles rotate asindicated by the arrows in Fig. 1. Upon the shafts of gears 10 and 12,which shafts are also mounted in the plate 3, are cams 37 which engagein their rotation, the gathering fingers 31 and for -e them into theposition edge of the mattress; springs 34 fixed to the plate 3 at oneend, engage the opposite sides of the fingers 31 and maintain saidfingers in positions to be actuated at the proper time by the cams. 'lhespur wheel 12 is trained to a spiral gear 17 through which the mattresstable is operated through anintermediate gear 13 which engages a lowergear 14, the shafts of both of said gears being mounted upon the plate3. llhe shaft 15 of said lower l gear] -1 carries a worm wheel 16' whichdrives the spiral gear 17 before referred to, the latter hei -g on shaft18 having bearings 19 on the plate 3 and in the side plate 1.

I Upon the shaft 18 there is a' spur Wheel 20 ing a rack 39 on the lowerside of the mattress table 5. The gear 21 is mounted upon an arm 22loose ,upon shaft 18. .By means of shown in Fig. 1 where they aregathering the which drives a smaller spur Wheel 21 engag.

, passing through a slot 23 in the side plate 1,

this arm 22 the gear 21 may be released from engagement with the rack 39when it is desired to stop the movement of the mattress table. Upon thefree end of the arm 22 there is a screw 41 penetrating the same and saidscrew being provided with a wing nut 24 by means of whieh it istightened against the plate 1 at any point within the range of the slot23. hen the mattress is thus prepared for stitching, the work ofstitching may be done by hand or by a machine; this operation has notbeen illustrated as it embodies 110 part of the present invention whichcomprises means solely for 'reparing the edge or edges of the mattress fzr stitching.

It will be understood that the needles 28 enter the opposite sides ofthe mattress in planes substantially at right angles to their positionsas shown in Fig. 1, and from the )ositions shown in dotted lines acrossthe lower gear 12. In the movements of" said needles, their paths aresubstantially as shown by the curved dotted lines in the mattressfilling. The said needles enter the mattress in straight lines, and astheir supporting wheels 10 and 12- rotate, they are moved downwardlyinto the mattress filling, then upwardly and outwardly and in theirupper and outward movementsthe filling of the mattress is pressed intothe edge immediately after which the bent ends 35 of the fingers engagethe mattress. In this sweeping movement of the needles, the giliideflanges 4 serve as pivots for said nee- As shown in the drawings, thereis one set of needles comprising two needles which are pivoted to thegears 10 and 12. it will be understood that the inner ends of theseneedles describe substantially the same path of movement as do the outerends. Each needle as it describes the circle ol its ino\e ment, iscaused to enter the edge of the mattress, and '[11 its sweeping movementis caused to press up the hlhng in the corner and to withdrawat thecompletion of each j lingers to cause them to engage the 114 3 rotationof its supporting gear. and to again make the circuit of its movement asthe} trated the same.
